LIS: Self-Defined Information Structures - Attribute Maintenance

Description

In Release 4.0A, it is possible to maintain attributes for information structures when you create self-defined information structures in Customizing.

You can use these attributes to define the type of an information structure (standard, without period, without updating, or standard with stock values) and also to specify whether this information structure os to be plannable.

The attributes are explained in detail below:

Types of Information Structures

The information structure type has been introduced in order for stock values to be displayed correctly and in accordance with customer requirements in self-defined info structures. Here, stock values correspond to the key date values. For example, the key figure valuated stock is such a stock value.

In the LIS applications 03 (Inventory Controlling ) and 40 (Retail), you can create these types without any restrictions. In all other applications, only the 'standard' type is of relevance.

When you create the individual types, this ensures that updating and the standard analysis are generated, and that it is possible to work with the LIS tools (planning Copy Management, etc.).

SAP Recommendation

In order to implement this recommendation, you require 3 information structures of the following types:

1. Info structure of type "standard" (movement structure)
2. Info structure of type "w/o period" (stock structure)
3. Info structure of type "w/o updating" (planning structure)

Here, the actual data is updated to the information structures of the types 'standard' and 'without period'.

The standard analysis (and planning) is based on the info structure of the type 'without updating'.

When reporting takes place, the system performs a retrospective calculation of the stock values using the current stock value and the periodically saved receipts/issues values from the 'standard' info structure.

Example 1: App. 03 (INVCO)

Example 2: App. 40 (RIS)

If you wish to use the info structure types, please refer to the information in the standard system (examples 1 and 2, when displaying the information structures and their updating definitions) when you create your own info structures.

When you implement the info structure of type 'without updating', the process for creating this type of info structure is slightly modified.

Once you have defined the info structure and its type, you also need to assign info structures of the types 'standard' and 'without period'.

If key figures are marked as stock value (checkbox StV) in the next screen, you need to use the additional pushbutton "Receipts/issues key figures" to assign receipts/issues key figures (back calculation of stock).

The sysytem performs a series of checks during creation and generation of the information structure.
Example:
Receipts/issues key figures must also be available in the info structure of type 'standard' as well as in the info structure of type 'without updating' that you are creating.

In Release 4.0A it is only partly possible to use the planning tools (creating planning hierarchies, forecasting, etc.) as only actual data is contained in this info structure.
In this case you need to copy the actual data from the assigned 'standard' info structure to the 'without updating' info structure.

'Standard (with stock values)' Info Structure Type

The SAP recommendation (using the method described above to depict stock values) has the advantage that no background processing is necessary (period closing program, entering inventory data at period closing)

If, however, a customer requires stock values to be saved alongside historical values at regular intervals (this should be realized in a customer project), then you need to create an info structure of type 'standard (with stock values)'.
Benefit: Performance is improved during reporting.

The same applies to legacy data (e.g. stocks) that has been imported to R/3 by means of the LIS inbound interface. Here you need to mark the stock values you require as such (by putting a tick in the 'StV' field).

Here it is not necessary to assign other info structures or receipts/issues key figures. An example of the type Standard (with stock values) is not available in the standard system at present.

Relevance for Planning

When you create a self-defined info structure, you need to decide whether this is relevant for LIS planning.

It is not possible to mark an info structure of type 'C' as being relevant for planning.

LIS planning is possible for all self-defined info structures that have been created up till now (upwards compatibility).

Please note that you should be sure whether the info structure you are creating should be planned or not, because performance levels are considerably better during reporting for an unplannable info structure.

In the case of an info structure that is not relevant for planning, the system converts the existing key, so that those fields that are not relevant to access (SSOUR, period fields that are not required) are placed at the end of the key.
This speeds up the search in the database.

If the self-defined info structure is to be supplied with data, the primary index checks the respective database key.
Version 000 is alway included in the search criterion. The client is always in first place in the database key, otherwise every Data Dictionary table is interpreted as being client-independent. The characteristics are placed directly after the client in the database key. The database key is thus organized as follows:

Client - Characteristics - Version - ...

When updating is actiavted, the database key is converted once more so that the search criteria for updating are placed nearer the beginning.

Example:

Client - Month - Characteristics - Version - ...
